MTN South Africa- Useless customer service and support

After upgrading 2 years ago, realising I am not getting any updates to upgrade, I started investigating as to why. It came to light that MTN incorrectly booked my 24 month contract with a 24month monthly amount on a 36month plan. Trying to get this fixed has been an ongoing relentless and frustrating process and been going for 2 months, with endless calls everytime with a so called better customer support, with over 25emails up and down. They have even shared an investigation report where the mistake is verfied yet when I follow up if I can go ahead and if there will be reimbursment then the next customer support operator has absolutely no clue whats going on.

This has now reached the point where I will cancel my contract after being with MTN for 22years now.

Absolutely pathetic!
